An asterisk ( * ) indicates the default context, an at sign (@) indicates an abbreviation, and under the prefixes column, SI indicates that the unit takes all SI prefixes, IEC indicates that the unit takes IEC prefixes, and SI+ and SI- indicate that the unit takes only positive and negative SI prefixes, respectively.  Refer to a unit in the Units package by indexing the name or symbol with the context, for example, becquerel[SI] or Ci[radiation]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, becquerel or Ci.

  

 

  

The units of radioactivity are defined as follows.

  

A becquerel is defined as a radionuclide decay per second.

  

A curie is defined as 3.71010 radionuclide decays per second.

  

A rutherford is defined as 1.106 radionuclide decays per second.
